ENGINEERING PLASTICS AND POLYURETHANES FOR AUTOMOTIVE ELECTRICS

Innovation in automotive design is driven by electrical, electronic and mechatronic systems. New driver assistance systems, interconnected mobility and electromobility will accelerate this development even further. Engineering plas-tics often enable innovative solutions which make electronic systems indispensable when it comes to safety, comfort and energy efficiency in modern vehicle concepts. From a simple fuse to state-of-the-art power electronics there is hardly an application that does not rely on plastics. In fact, through high-performance thermoplastics these applica-tions have often become reliable and economically feasible.

Where electricity flows, plastics have to show excellent electrical properties, good mechanical performance and high dimensional stability under heat. In automotive appli-cations, extremely high requirements such as resistance to media and to weathering as well as heat aging resistance have to be fulfilled. Other recurring topics are miniaturiza-tion and weight saving.

3 | Products and applications

3.1 Ultramid®

BASF’s Ultramid® grades are molding compounds based on PA6, PA66, various co-polyamides such as PA66/6 and partially aromatic polyamide. Its outstanding mechani-cal strength and toughness, proven resistance to different media, its electrical insulating properties and excellent processability make Ultramid® a material that has become firmly established in almost all areas of automotive elec-trics and electronics.

Ultramid® allows extremely robust designs required in automotive engineering for wire-to-wire and wire-to-board connectors. Its excellent toughness and resistance to vibrations ensure reliable operation, even under adverse environmental conditions.

PRODUCTS AND APPLICATIONSUltramid®

This also enables robust handling in assembly and main-tenance work. The good processability helps to produce complex connectors, latching and locking systems as well as to manufacture them economically in multi-cavity molds. Metal parts, contact pins or cables can be tightly overmolded directly in the mold. Thanks to the excellent toughness and weld line strength, metal contacts can also be pressed into the plastic body and crimp contacts can be clipped in. Elastic seals based on silicone or TPE6) (e. g. Elastollan®) can be overmolded with good adhesion using multi-component injection molding. The possibility to use snap-fits or film hinges also expands design options for the designer.

The Ultramid® product range offers tailor-made materials for almost any connector application. Both PA6 and PA66 are available unreinforced or with glass fiber contents from 15 to 50 percent. Various stabilizer systems or impact-mod-ified products make it easier for engineers to optimally meet their requirements. Typical materials for use in connectors are Ultramid® B3EG6 and Ultramid® A3EG7. Increasingly tougher operating conditions result in more requirements regarding operating temperatures, climate testing, media tightness or vibration strength. Thus, the suitable materials have to be chosen with care. Thanks to BASF’s wide range of products and many years of ex-perience, our experts are able to find the best solution for the specified application purpose.

Ultramid® is a proven material for large and complex compo-nents such as fuse and relay boxes, which can be installed both in the interior and directly in the engine compartment. Today, these electromechanical units, which are often com-prised of several individual modules, are not just used to supply or distribute power and prevent short-circuits.


They also increasingly integrate central control functions. This reduces the complexity of the electrical system and thus the mounting space, weight, and the susceptibility to failure. With the many different design options offered by Ultramid®, optimum solutions can be found for all installa-tion situations. For example, snap-fits simplify the assem-bly of modules for flexible platform concepts. PA6 is the preferred material when it comes to meet requirements for a long service life. For example, Ultramid® B3WG6 or the impact-modified B3ZG3 have been proven materials for a long time. For housings and covers, special materials filled with glass fibers, glass beads and/or minerals such as Ultramid® B3GK24 or B3WGM24 are also available.

Highly filled products such as Ultramid® B3WG10 with 50 percent glass fiber content are suitable for components under high mechanical loads. They can be used for exam-ple to support or hold heavy starter batteries.

Components made from Ultramid® are perfectly compat-ible with the fluids and lubricants typically used in auto-mobiles. They often replace even metal parts. The great freedom of design and the versatile methods of plastic processing make it easy to integrate additional functions, to best use space and to achieve maximum weight sav-ings. For components in the engine bay such as sensors, valves or switch and pump components, which are not in direct contact with the coolant, Ultramid® B3WG6 and Ultramid® A3WG6 are generally used. For components in continuous contact with cooling fluid, Ultramid® A3HG6 HR and Ultramid® A3WG6 HRX, which are particularly hydrolysis-resistant, show superior water and glycol resis-tance. In addition, many other components made from Ultramid® can be found under the hood ranging from cable ducts and air-flap systems to electrical steering systems.

For electric fans, fan shrouds and fan control units, prod-ucts such as Ultramid® B3WG5, B3WG6 or A3WG6 are a popular choice because they are very well able to cope with the tough operating conditions in the engine compart-ment. Even large and complex fans are feasible. The many different design options help designers to optimize efficien-cy and noise emissions. Glass- or mineral-filled products such as Ultramid® B3WGM24 or Ultramid® B3WGM45 are used mainly for shrouds and enclosures.

For sensor applications, Ultramid® has established itself as a robust and versatile housing material. It is used, for example, for oil sensors or wheel speed sensors. Oil sen-sors measure the oil level and/or oil quality in the engine oil circuit. They function so reliably that they are gradually replacing the traditional oil dipstick. Typical sensor products are Ultramid® A3WG6, A3HG5, A3EG5 and B3WG6 for wheel sensors.

Modern automatic and dual-clutch transmissions are increasingly integrating the transmission control unit as a mechatronic assembly mounted directly into the trans-mission. Eliminating interfaces, cables and connectors makes the control units smaller and lighter. This also helps to reduce their susceptibility to faults and improves shift-ing comfort. In some cases, the control units are seated directly in the transmission oil.


Oil sensor

They have to withstand oil temperatures of up to 140 °C and even higher peak temperatures as well as show good compatibility with modern transmission oils. Ultramid® A3WG6 and A3HG7 have proven to be very well suited for this extremely demanding application. These products allow the tight overmolding of what are known as punched tracks or grids. They are used for the electrical connec-tion of the control unit. Another important aspect is good vibration resistance of the components fitted directly to the transmission.

For applications involving particularly sensitive electronic components, BASF has developed high-purity plastics in special electronic qualities. Products such as Ultramid® A3EG6 EQ or A3EG7 EQ help to further improve the ser-vice life and reliability of electronic systems (details see section 4.3). Our experts can provide valuable help in choosing the right product.

In the automotive industry, the laser marking of compo-nents is used as a flexible, secure and permanent marking method, e. g. for the production control system or for trace-ability in case of failure. This replaces, for example, adhe-sive labels which are less durable. For laser marking and the modern joining technique of laser welding, BASF offers specially modified versions of Ultramid® such as Ultramid® A3WG6 LS or Ultramid® A3EG6 LT. “LS” is for laser-sensi-tive and “LS” for laser-transparent in laser welding applica-tions. BASF has many years of experience and offers cus-tomers expert support in choosing the right material and optimizing the process used.

Section 4.2 describes the benefits and possibilities of laser welding, which is known, for example, from the fabrication of radio transmitter keys and sensor covers.

Ultramid® is frequently found in control elements inside the car, where its great toughness makes it ideal for steering column stalks and levers. These parts have to be extre-mely robust, but must not pose any risk of injury in case of a crash. A good and low-wearing surface is also requi-red as well as printability or high-contrast laser marking of symbols. Besides, long-term resistance to hand sweat, grease, cosmetics or sunscreen is also of high importance. This is generally possible with partially crystalline materials such as Ultramid®.

Most Ultramid® grades meet the standard automotive requirements for fire safety in line with FMVSS 302 and DIN 75200 or ISO 3795. For additional requirements such as those in the commercial vehicle sector in line with ISO16750, a wide range of flame-retardant grades is available. It com-prises predominantly halogen-free flame-retardant com-pounds, such as Ultramid® A3X2G5, A3X2G7, A3X2G10, A3XZG5, A3U40G5, A3U41G5 SI, A3U42G6 and Ultramid® T KR4365 G5. In case of fire, these products also show an extremely low smoke gas density and smoke gas toxicity. In their material class they achieve the best flame-retardant stability and thus low deposit formation. They are easy and economical to process. Products such as Ultramid® A3UG5 even meet the requirements of Bosch Standard N 2580-1 for ingredients of components. They can be equipped to be laser-markable.

In addition to the flame-retardant polyamides described above, BASF also offers a wide selection of other flame-retardant products. Detailed information is compiled in the brochure “Engineering plastics for the E & E industry”.

Ultramid® T

In comparison to other polyamides, the partially aromatic Ultramid® T (PA 6T/6) offers a very good level of toughness and a high level of dimensional stability under heat. It also shows mechanical properties which remain mainly con-stant both in the dry and wet states. This favorable property range is complemented by good chemical resistance and dimensional stability. Ultramid® T is suitable, for example, for connectors or sensor components which come into direct contact with corrosive fuels such as bio-fuels.

In addition, Ultramid® T shows good resistance to calcium chloride (CaCl2). It thus meets the more stringent require-ments regarding the resistance to salt spray in regions such as the USA, Russia or Japan, where road salts containing calcium are mainly being used.

With a melting point of 295 °C, Ultramid® T is also ideal for use in SMD7) components and lead-free soldering tech-nologies. Details on this can be found in Section 4.4.

The Ultramid® product range is continuously optimized and expanded for the ever-changing requirements of our cus-tomers. The following chapters describe a number of spe-cial products and new developments which make possible new solutions in automotive electrics and electronics.

Ultramid® Balance

Ultramid® Balance is a material family based on PA6.10 with an interesting property profile. It shows high resistance to fuels, hydrolytic media and salt solutions such as calcium chloride or zinc chloride. It is therefore an interesting alterna-tive to other long-chain high-performance polyamides such as PA6.12 or PA12.

Thanks to its lower water absorption, Ultramid® Balance is more dimensionally stable than PA6 or PA66. Its mechanical properties are less susceptible to environmental conditions or moisture content. Compared to PA12, it is more solid and rigid. It also shows better dimensional stability under heat.

Products such as Ultramid® S3EG6 Balance or A3HG6 Bal-ance are very well suited for wheel sensors or other compo-nents which are exposed directly to salt spray. They can also be used for housings and components which require a high level of dimensional stability in critical installation situations or under extreme climatic conditions.

Ultramid® Endure

Ultramid® Endure is a new glass fiber-reinforced polyamide with outstanding heat aging resistance. It effortlessly with-stands constant loading for over 3,000 hours at 220 °C and brief temperature peaks of up to 240 °C. It is thus suitable for housings or sensor applications in charged air and intercool-er systems, exhaust gas recirculation or other temperature-critical installation locations.

Ultramid® Structure LFX

Ultramid® Structure is a high-performance plastic which is reinforced with long glass fibers. Where even optimized short glass fiber-reinforced plastics reach their limits, Ultramid® Structure offers new opportunities for the elec-trical equipment in vehicle manufacturing. This polyamide has a property range that is unique for plastics. It is a major step forward when it comes to replacing metal. The high-performance plastic is particularly suitable for use in components which are exposed to high levels of stress and where designers previously choose metal.

3.2 Ultradur®

Because of its special combination of properties, Ultradur®, the polybutylene terephthalate (PBT) from BASF, is an ideal material for many applications in automotive electrics and electronics. As a result, it has long been established in all areas of automotive electronics systems. In addition to high rigidity and excellent heat resistance, it shows outstanding dimensional stability, good resistance to weathering and superior long-term electrical and thermal performance. Of particular significance for automotive electronics is the low water absorption and thus the fact that the mechanical and electrical properties are largely independent of moisture content or climatic conditions. Ultradur® is an indispensable material in particular for safety-critical components which have to work safely and reliably throughout the entire lifetime of a car.

Ultradur® is established as the first-choice material for ECU8) housings by all the leading manufacturers and OEMs around the world. The range of applications covers the entire range of comfort control units, including seat and door modules, right through to safety-critical ABS9)/ESP10) systems, SRS or airbag control units or electrical steering and braking sys-tems. Typical materials are Ultradur® B 4300 G4 and B 4300 G6. Metal inlays, contacts or punched tracks and grids can be overmolded more efficiently and the excellent dimensional stability guarantees that multi-pole connectors function steadily.

Ultradur® grades are available as laser-markable versions, which is particularly important for safety-critical compo-nents. This means that for example component data can be applied directly and permanently to the surface of the plas-tic via “Data Matrix Code”. So the data is easy to read and makes counterfeiting more difficult. Details on the laser weld-ing of Ultradur® are summarized in Section 4.2.

PRODUCTS AND APPLICATIONSUltradur®

17

Ultradur® is also used in some transmission control units of automatic transmissions which are fitted directly in the transmission. Without interfaces, cables and connectors, the functional integration makes these mechatronic con-trol units smaller, lighter and reduces their susceptibility to faults. A typical grade for this extremely demanding appli-cation is Ultradur® B 4300 G6.

Ultradur® is indispensable as housing material. The range of applications extends from pressure or temperature sensors and mass air flow meters to acceleration and steering angle sensors. The sensor can be designed either as an indepen-dent unit or as an integrated component in more complex assemblies. Robust housings made from Ultradur® are also used to protect, among others, modern MEMS11) sensors. They thus ensure the high reliability of these components in the long run. This is extremely important for safety-critical functions such as airbag or ESP systems. Ultradur® is also ideally suited for ultrasonic, radar, laser and video sensor technology. It thus helps to make modern driver assistance systems more reliable, comfortable and affordable.

Its suitability for dimensionally stable, thin-walled hous-ings in combination with stable electrical properties make Ultradur® the ideal material for ignition coil modules which can be mounted directly in the cylinder head. The coils can be fixed and sealed in place with the standard casting compounds.

With the improved flowability of the Ultradur® High Speed grade delicate and thin-walled molded parts, which were previously barely conceivable, are now feasible. In addi-tion to weight advantages, this also allows smaller instal-lation spaces or improved productivity thanks to shorter cycle times.

11) MEMS = Micro-electromechanical systems


18

The balanced combination of the properties makes Ultradur® the obvious choice for many wire-to-wire and wire-to-board connectors which must have high dimensional stability and low warpage. Especially compared with polyamide, the very low moisture absorption ensures small dimensional changes and very constant properties in changing climatic conditions.

Apart from unreinforced products such as Ultradur® B 4520, the product range features a selection of glass fiber-reinforced grades such as Ultradur® B 4300 G2, B 4300 G4 and B 4300 G6.

All these products are also available in a High Speed version with even better flowability for connectors with extremely thin walls. The easy-flowing Ultradur® High Speed grades are the perfect choice because they are suitable for small grid dimensions and often allow shorter cycle times. In addition, an easy-flowing grade with 15 percent glass fiber reinforce-ment is available as Ultradur® B 4300 G3 High Speed. BASF offers the right material for almost any kind of connector type.

Ultradur® is furthermore used for housing applications which are subjected to high mechanical loads and where rigid, complicated geometries with good dimensional stability are required. Where multi-part modules have to be fitted or tol-erance-sensitive assemblies such as gear transmissions or lever actuators have to be securely enclosed, the glass fiber-reinforced Ultradur® grades B 4300 G2, B 4300 G4, and B 4300 G6 are widely used.

Similar requirements apply for steering column modules as well as axial and radial fans used for interior ventilation and air-conditioning or for cooling fans of electrical devices. If necessary, flame-retardant grades are available.

Its excellent tribological properties and high wear resistance make Ultradur® suitable for components and sliding ele-ments which are subject to friction. Typical applications are housings and functional parts of electric window winders, seat adjusters, sunroofs, mirror actuators or locking systems.


20

Ultradur® S

Ultradur® S (PBT/ASA) was specially developed for housing applications which require even better dimensional stabil-ity, a high level of complexity, low frictional wear or good surface quality together with high economic efficiency. Examples are door control units or the actuators housings for which Ultradur® S 4090 G4 or S 4090 G6 are used.

In order to make it easier for molders to create complex components, BASF offers optimized grades such as Ultradur® S 4090 GX, S 4090 G4X and S 4090 G6X. These materi-als have lower contents of anisotropic fillers, reinforcing materials and improved demolding properties. Thus, they are the best basis for the economic production of large and complex components. Ultradur® S is resistant to light expo-sure and elevated temperatures near the windshield. It is even suitable for components on the top of the dashboard. Examples are air-conditioning components such as diffuse fields, air distributors, ventilation grilles, air flaps and actua-tors as well as solar or temperature sensors.

Door control unit

Diffuse field

Ultradur® S grades are also available as easy-flowing ver-sions such as Ultradur® S 4090 G4 High Speed and S 4090 G6 High Speed. They combine design freedom and economic efficiency.

Ultradur® is generally suitable for exterior applications due to good resistance to UV light and weathering. Molded parts made from Ultradur® barely tend to yellowing and their sur-face hardly changes. The mechanical properties such as rigidity and tensile strength are rarely impaired. However, parts for exterior applications should be colored black. The most suitable products for parts which are heavily exposed are Ultradur® B 4040 G4 and B 4040 G6: They have an outstanding surface quality together with high UV stability. Examples of exterior applications are door handles and lock-ing systems, wiper/washer systems, mirror mechanisms, sunroof components, air flap systems, exterior sensors or aerials. Parts made from Ultradur® can be easily coated.


21

Headlamp bezel

Especially for lamp frames and headlight bezels, Ultradur® B 4570 is a low-emission high-gloss product, which shows extremely low levels of degassing, even when used over a long period of time at temperatures of up to 160 °C. This reduces the risk of headlamp lenses becoming cloudy as a result of condensing ingredients. BASF’s PBT portfolio for headlamps includes Ultradur® B 4520 for standard applica-tions, Ultradur® B 4560 with optimized demolding proper-ties, Ultradur® S 4090 with particularly good flowability and low warpage and Ultradur® B 4570.

Ultradur® is in general resistant to calcium chloride and zinc chloride. Thus, it meets the stringent requirements for resis-tance to salt spray in regions where road salt with calcium is used.

Most Ultradur® grades meet the standard requirements in vehicle manufacturing for fire safety in line with FMVSS 302 and DIN 75200 or ISO 3795. If products in line with ISO 16750 are required, BASF offers several flame-retardant grades.

Furthermore, BASF provides established flame-retardant products of the Ultradur® B 4406 range and halogen-free products, such as Ultradur® B 4441 G5 and Ultradur® B 4450 G5. Detailed information about these and other flame-retardant compounds can be found in the brochure “Engineering plastics for the E & E industry”. The Ultradur® product range is continuously optimized and expanded in order to fulfill changing requirements of our customers. The following sections describe a number of special prod-ucts and new developments for new solutions in automo-tive electrics and electronics.

Ultradur® HR

With the development of the hydrolysis-resistant Ultradur® HR grades, the ever-growing requirements of the automo-tive industry for climate testing and thermal aging have been taken into account.

The newly developed Ultradur® B 4330 G3 HR and B 4330 G6 HR are ideal for connectors which need to qualify for SAE USCAR-2 Component Class 5 for cli-mate change testing at higher operating temperatures. The hydrolysis-resistant Ultradur® HR is already used as housing material for the latest generations of ABS/ESP control units. In long-term tests at 85 °C and with 85 % relative humidity, it does not show any notable signs of aging even after 5,000 hours. This grade helps to greatly improve reliability and failsafe quality of safety-relevant electronic components in the long run. With Ultradur® B 4330G3 HR HSP, BASF also offers a very free-flowing grade with 15 % glass fibers.

Ultradur® B4300 C3 LS

With Ultradur® B4300 C3 LS, a carbon-fiber reinforced Ultradur® is on the market for the first time. It features low electrostatic charge along with good conductivity. Due to the anti-static properties, less dust or dirt adheres to the component. The product absorbs hardly any water and is laser-markable. Furthermore, it can be easily combined with other PBT grades, e. g. by welding or bonding, and is also suitable for complex, thin-walled components. Possible applications for this carbon fiber-reinforced PBT are parts with gases or fluids flowing through, elements that are subject to static charge due to friction and applica-tions that require ESD ( = electrostatic discharge ) protection. Moreover, components made of carbon-fiber reinforced Ultradur® are more reliable and more long-term resistant than plastics equipped with conventional anti-statics, as these additives are known to migrate to the surface and tend to lose their anti-static effect with time. The BASF material thus helps to fulfill the increasing demands on min-iaturization, precision and security of parts in automotive electrics.

3.3 Ultrason®

BASF’s Ultrason® grades are amorphous thermoplastics which include polysulfone (PSU), polyethersulfone (PES) and polyphenylensulfone (PPSU). They are characterized by a very high heat resistance. Their special qualities are high dimensional stability as well as good, largely temper-ature-independent electrical and mechanical properties. Ultrason® is inherently flame-retardant. Many grades meet UL 94 V-0 without any additive. This property profile and its good electrical insulating capacity, high heat aging resistance and good resistance to hydrolysis, Ultrason® is particularly suitable for components which are subjected to high stresses over a wide temperature range from -50 °C to +180 °C. In the case of Ultrason® E, even tem-perature peaks of up to 220 °C are tolerable. BASF offers unreinforced products, which are transparent and thus quite unique for engineering plastics.

The main applications for polyethersulfones in automotive construction are headlamp reflectors and headlamp bezels. The high dimensional stability under heat and excellent sur-face quality are the perfect basis for manufacturing reflec-tors for headlamps as well as bezels, signal lamps and high-quality interior lighting. Even compact designs close to hot components or with unfavorable cooling conditions are feasible. The thermal expansion is consistently low over a wide temperature range. In addition to good process-ability, this helps to achieve an optimum design in reflector geometry. Hence, these compounds contribute to a high luminous efficiency, uniform illumination and a stable cut-off line for the headlamps.

Special IR-transparent colors such as Ultrason® E 2010 MR black HM (Heat Management) reduce the level of heat-ing caused by IR or thermal radiation. With Ultrason® as a reflector material, there is no limit to creativity for designers.

Direct metallization of surfaces is possible using typical methods such as PVD12). The good surface quality of molded parts leads to smooth and high-gloss reflector surfaces with good metal adhesion, e. g. of aluminum.

Where conventional thermoplastics reach their limits, Ultrason® is the ideal choice for components that have to withstand high thermal and mechanical loads, such as coil formers, sensors, plug-in connectors and functional parts of switches or relays. For example, Ultrason® is used for transmission connectors that have to be dimensionally stable at temperatures of up to 170 °C and show low swell-ing caused by the transmission oil.

On account of the good hydrolysis resistance, glass fiber-reinforced Ultrason® E 2010 G6 can be used for impellers of electrical coolant pumps. The high dimensional stability makes it easier to manufacture parts with narrow toler-ances; thus enhancing the efficiency and effectiveness of the pumps.

Pump impellers

Independent of the temperature load, the exceptionally good creep resistance makes Ultrason® attractive for com-ponents which have to withstand mechanical loads over long periods of time. Ultrason® can be used as thermal insulator or heat shield for heat-sensitive components.

The transparency of the unreinforced Ultrason® grades allows solutions which are not possible with other engineer-ing plastics. This transparency can be exploited especially for optical sensor components, displays or lamp covers.

Where high temperatures prevail and/or a high level of toughness or chemical resistance is required, this com-pound is the right choice. The good toughness can be used for shatter-proof transparent covers. It is an alterna-tive to glass or transparent plastics which are more liable to fracture. The relatively high optical refractive index of up to 1.7 makes it easier to design optical lenses or optical systems.

Transmission plug connectors

12) PVD = Physical Vapor Deposition


26

Ultrason® is also used for the transparent enclosures of blade fuses in the conventional formats such as Maxi, ATO, Mini and Low-profile, which are characteristically colored transparent. When the fuse blows, Ultrason® is able to with-stand the temperature peaks without any risk of ignition. The good chemical resistance makes it possible to use Ultrason® for applications in the fuel system. Components made from Ultrason® are even suitable for installation in fluorinated fuel tanks, used for the purpose of reducing fuel permeation. In addition, Ultrason® E (PESU) and Ultrason® P (PPSU) show excellent resistance to the test gasoline FAM B, which is a real challenge for many other plastics.

3.4 Ultraform®

Ultraform® is the brand name for BASF’s range of thermo-plastic co-polymeric polyoxymethylenes (POM). The special feature of Ultraform® is the ideal combination of strength, stiffness and toughness, which derive from its chemical structure. Owing to its high crystallinity, Ultraform® is stiffer and stronger than other engineering plastics, especially within the temperature range from 50 °C to 120 °C. This com-pound shows no transformation between the low glass-tran-sition temperature of approximately -65 °C and the melting temperature of approximately 170 °C. This results in constant mechanical properties over a wide temperature range, which is interesting from a technical point of view.

At room temperature, Ultraform® has a distinct yield point at about 8 to 10 percent strain. Below this limit, Ultraform® shows good resilience, even under repeated loading. It is therefore especially suitable for elastic spring elements. In addition, it has a high creep strength and a low tendency to creep. This combination, together with high surface hard-ness as well as good frictional and wear properties, makes it suitable for many engineering applications.

Ultraform® is exceptionally resistant to many of the lubri-cants, fuels and chemicals used in automobiles, even at elevated media temperatures. An important field for Ultraform® is the entire area of fuel supply for both gaso-line and diesel vehicles. Applications range from a com-plete fuel delivery module made from Ultraform® S2320 or N2200 G43, which is fitted right in the gas tank of the vehicle, to fuel meters, flow sensors or valves. Resistance to high alcohol admixtures and various bio-fuels is a matter of course.

In order to meet the requirements of SAE Standard J1645, Ultraform® N2320C has been developed. This is an elec-trically conductive material which prevents electrostatic charge and the risk of sparking in the fuel system. In test conditions in accordance with ISO 3915 (four-point meth-od), this product achieves a value of just about 30 Ω · cm. It thus significantly exceeds the requirements of SAE J1645. Ultraform® is very resistant to urea solutions such as those used in AdBlue® technology for the selective catalytic reduc-tion (SCR) of diesel exhaust gases. Ultraform® is suitable for many functional parts in direct contact with AdBlue®, for example fuel meters, pumps, connectors, valves or meter-ing devices.

Fuel delivery module

Loudspeaker grilles

Fuel filter made from Ultraform® N2320C

On account of its good tribological properties, Ultraform® is suitable for all applications where good sliding friction properties and low wear rates are important. Typical appli-cations are gears, sliding elements of drives and actuators such as window winders, mirror adjusters or lock systems.


29

Components made from Ultraform®

Due to the excellent resilience of Ultraform®, spring func-tions can be integrated directly into a component and make additional metal springs redundant. This can simplify assembly and improve reliability. Examples are controls, buttons, switches and microswitches. The well-directed use of Ultraform® can have a positive influence on the touch, feel and sound of control buttons.

Restrictions apply to the use of Ultraform® for exterior applications. It can be used for electric drives for mirrors, headlamp levelers, bend light actuators, for wiper/washer systems, clips and fastening elements and many more. However, direct exposure to sunlight should be avoided.

In the interior, Ultraform® is used for delicate loudspeaker covers. It replaces less robust plastics or expanded metal mesh. The high strength, toughness, scratch resistance and the good mechanical resilience protects grilles and loudspeakers when being kicked or bumped. Ultraform® helps to permanently prevent unpleasant rattles, squeaks or disruptive noises caused by distortions and vibrations during vehicle operation as well as buzzing and droning caused by loudspeaker excitation. The good processability of Ultraform® permits thin-walled and delicate structures. This in turn can have a positive impact on the quality of the sound of the speaker system. For interior applications, low-odor products with optimized emission behavior are available (suffix: LEV). Detailed information about Ultraform® can be found in the brochure “Ultraform®”.

3.5 Elastollan®

The high-performance material Elastollan® is BASF’s ther-moplastic polyurethane (TPU). These thermoplastic elasto-mers are available in a hardness range of approx. 35 Shore A to 83 Shore D.

The products are characterised by the following properties:

high wear and abrasion resistance high tensile strength and excellent tear propagation resistance

very good damping capacity very good low-temperature flexibility high resistance to oils, greases, oxygen, UV and ozone

Oil and grease resistance are the main characteristics of the polyester-based Elastollan® grades; the polyether-based Elastollan® grades offer good cut resistance, high tear strength and tear propagation resistance, as well as outstanding hydrolysis stability, low-temperature flexibility and microbial resistance.

This combination of properties has made Elastollan® very successful, even in very demanding applications in auto-motive electrical and electronic systems. The application scope ranges from simple grommets to complex housing seals and sheathing for high-voltage cables.

Elastollan® sheathings for cables and connectors meet the most demanding criteria for protecting valuable and sensitive wiring. The significantly contribute to operational reliability and safety. Elastollan®-sheathed cables provide a safe flow of energy and data, both for interior applications and for more extreme environments in the engine compart-ment or in the wheel well subject to stone impact, water and low temperatures.

High-quality cable sheathings and wiring components are essential, particularly in electromobility, to safely and dura-bly meet the wide variety of technical demands for high-voltage, traction and charging cables.

Products in the Elastollan® 11 range, such as Elastollan® 1185 A 10, 1185 A 10 M and 1195 A 10, have proved suc-cessful for many years both for cables and for high-volt-age cables with operating temperatures of -40 °C through to 125 °C (ISO 6722 Class C).

The “High Performance Material” Elastollan® 785 A HPM was developed for higher operating temperatures of up to approx. 150 °C (ISO 6722 Class D). It also meets the more stringent demands of temperature class D of Ger-man automotive manufacturer delivery specification LV 112; in some cases, the standard specifications are even exceeded.

As well as the “soft” Elastollan® 785 A 10 HPM with a hardness of 85 Shore A, BASF also offers the consider-ably harder Elastollan® 754 D 15 HPM (Shore D 53). In contrast to the softer material which is recommended for thicker walls that are found in sheathed cables and bat-tery leads, Elastollan® 754 D 15 HPM is suitable for very thin core insulation. This product currently achieves the resistance required by ISO 6722 in humid heat over 1,000 hours.

PRODUCTS AND APPLICATIONSElastollan®

Alternative plastics which exhibit a comparable perfor-mance in this respect are either considerably more expen-sive because they come from even higher temperature classes, or more complex and thus more cost-intensive in processing. This applies in particular to crosslinked materials that also have the disadvantage that they are not recyclable and cause problems with water tightness when connectors and bushes are injected.

With charging cables, Elastollan® can be used to produce thin, lightweight and, even at low temperatures, flexible cables and coiled cables. They make handling during charging easier for the car owner who also can store the cables more easily.

For special applications there are also halogen-free flame-retardant Elastollan® grades. Elastollan® 1185 A10 FHF, 1185 A10 HFFR, 1190 A10 FHF and 1192 A11 FHF have proved extremely suitable for extruded cables. Elastollan® 1192 A11 FHF also has improved flame retardance, mak-ing it ideal as cable sheathing for thin-walled UL-approved leads. Elastollan® 1185 A10 HFFR has a particularly low smoke gas formation and toxicity, for example for coach and rail applications.

Cable

The increasingly more complex wiring technology in modern cars often face restrictions regarding installation space. In certain situations, flat conductors with Elastollan® sheathing can offer a solution: they are light, easy to assemble, require little space and give greater performance and safety.

Flat conductors

Plug-in connector

grommet

Apart from cable sheaths, plug-in connectors, grommets, kink-resistant sleeves are made from Elastollan®. Direct over-molding allows for watertight, heavy-duty assemblies, comprised of cable sheath, contact carrier and sleeve, even when combining different grades of Elastollan®. Every single element also has high wear and abrasion resistance. For example, Elastollan® 1175 A10 W has established itself as a reliable material for kink-resistant sleeves in ABS and ESP wire harnesses.

Contact carriers and plug-in connectors that demand excel-lent impact strength with high rigidity and at the same time good elongation, low coefficient of thermal expansion and low shrinkage can be manufactured efficiently with the glass fiber-reinforced polyester-based Elastollan® R3000. It also has outstanding electrical properties with a high tracking resistance (CTI=600).


33

Elastollan® is also ideal for high-quality seals to reliably seal, for example, electronic housings, tops or covers against environmental influences and a wide variety of media. The seals are normally injected in a two-component injection molding process onto the housing materials ready for assembly.

Cable sheathing

Elastollan® shows predominantly good adhesion to the housing materials widely used in automotive electrics such as Ultramid® (PA) and Ultradur® (PBT).

Sealing


34

Angled pieces and multiple outlet points are nowadays indispensable for a modern harness. Connectors and fasterners for later assembly of the harness are foamed in a single process step. The demand of the automotive industry to wire ever more electronic components in ever smaller spaces is met by PU foam technology. Elastofoam® I 4610/101, for example, has proved useful also for very demanding solutions.

Polyurethane grommets made, for example, from Elastofoam® I 4610/111 are preferably used where reli-able, one hundred-percent sealing of areas susceptible to moisture against creep water is required, for example at the inlet of electronic module boxes, control equipment, sensors or central electrics. Also in the grommet from the engine compartment to the car interior, the required lon-gitudinal water tightness is more and more often guaran-teed by polyurethane grommets or polyurethane sealing. The conventional fitting of cable sets with rubber sleeves, shrink tubing or cold-melt processes is very labour-inten-sive and often no longer meets today’s requirements for sealing, process safety and productivity. A combination of materials such as a polyurethane grommet and a rubber sleeve is being used for certain applications.

Cable sheathings

3.6 Elastofoam®

Elastofoam® is BASF’s tradename for its polyurethane flexible integral foam systems. They can be found in the automotive industry wherever the highest level of design freedom and a very high degree of comfort are required as well as optics and haptics and complex physical demands. Flexible integral systems are widely used in vehicle electrics, predominantly in the production of cable sets and wiring harnesses, and also as a material for encapsulating connectors, for embedding entire wiring harnesses in foam and as a material for grom-mets and sleeves.

Where high dimensional stability is required due to restrict-ed space available for installation or where wiring harness-es have to be protected from mechanical damage, specially customized polyurethane systems such as Elastofoam® I 4610/101 can fulfil these demands with minimum space requirement. The final assembly of the wiring harness is made easier by adapting the harness to the respective installation situation in the vehicle, and by foaming inserts and connectors in place in one process step. Foam encap-sulation replaces and supplements other types of sheathing such as cable ducts, corrugated pipes and hoses.

The possibilities for three-dimensional design can also be applied to partial and complete harness foam encapsula-tion. In these so-called dimensionally stable harness sets which are increasingly being used not only for cars but also for commercial vehicles, up to several hundred single conductors can be combined and produced in virtually any form.

PRODUCTS AND APPLICATIONSElastofoam®

35

Foam technology, however, offers a high level of process safety and productivity as well as the possibility to combine several functions. One single procedure replaces a whole chain of process steps. During foaming, the low-viscosity reaction mixture flows into the areas between the wires, encapsulates each individual wire, cures and thus reliably seals the harness. With the optimal coordination of foam system, mold geometry, mold and foaming process, foamed grommets can be accurately positioned on the har-ness with a closed foam surface. Because of the adapted hardness and flexibility of the foam the grommets can be fit-ted accurately and sealed reliably.

In general all products and processes must meet the usual test standards in the automotive industry or special internal specifications by the harness manufacturers. The test cat-alogue may call for the following tests or evidence (excerpt):

3.7 Cellasto®

The high-performance elastomer Cellasto® is a polyure-thane-based microcellular foam. BASF uses Cellasto® to produce vibration control components and semi-finished products. The most well-known applications are spring aids, top mounts and spring isolators. Their properties make them particularly suitable for vehicles with alternative drive concepts.

Cellasto® is particularly well suited to meet the vibration demands of electromobility. It is

compact and efficient – high level of deformation in restricted installation spaces

flexible and durable – good dynamic decoupling with optimum durability

lightweight with good damping properties – up to 30 % weight reduction with optimum damping and insulation properties

The amplitude-selective damping of Cellasto® leads to safe damping of component and system resonances with low dynamic stiffening and thus optimum vibration decoupling.

With spring aids made of Cellasto® it is possible to use lighter and more cost-effective steel springs with linear identification by progressively increasing the force, safely setting the final position and relieving the load on the surrounding structure due to its energy absorption and reduction of force peaks.

Elastic mounts made of Cellasto® are light, cost-optimised and efficient. They improve comfort and travel safety due to the particular static and dynamic properties of Cellasto®.

Spring isolators made of Cellasto® insulate roughness and damp spring resonances effectively, so that there is a significant NVH advantage (NVH = noise, vibration, harsh-ness), particularly in vehicles where lightweight construc-tion is a major consideration.

Shock absorber

PRODUCTS AND APPLICATIONSCellasto®

37

The particular properties of Cellasto® are a major advan-tage over conventional elastic mounts, particularly in engine and powertrain mounts for electric vehicles. High-frequency noise is effectively decoupled. This is a particularly impor-tant consideration because the vibration behaviour of electric engines differs greatly from that of combustion engines. High forces act here due to high-torque engines with high-frequency vibrations on the bearing positions. At the same time, weight savings of approximately 30 % can be achieved by Cellasto® itself, as well as by optimization on the interfaces.

Cellasto® offers amplitude-selective damping and the pos-sibility of achieving enormous deformations in compact installation spaces. Thus even heavy batteries for electric vehicles can be mounted effectively. In certain cases, it is even possible to use the weight of the battery as a weight-neutral dynamic vibration absorber.

4.1 Electromobility

Electromobility is an interesting field where experts antici-pate a high growth potential in the coming years. Energy-efficient electromobility is a key technology in transforming individual mobility as well as to make it more environmen-tally friendly. BASF focuses on research and development activities ranging from battery technology and lightweight construction to intelligent heat management and innova-tive materials.

Many e-mobility solutions can only be implemented reli-ably and efficiently by using highly versatile plastics.

BASF’s wide product range helps our customers to find the best material for many of these new and demanding applications. Our experts assist in developing new solu-tions and concepts as well as putting them into practice.

One focus is placed on battery systems of hybrid or elec-tric vehicles. The key to the success of electromobility will be how quickly the performance, capacity, weight, safety, reliability and above all these, the manufacturing costs and economic efficiency of the battery systems can be improved further. Engineering plastics can make a vital contribution to optimizing the system as a whole and enabling mass production that is economically viable.

Depending on the specific requirements Ultradur®, Ultradur® S, Ultramid® and possibly Ultrason® are suitable for the bat-tery or cell frames of lithium-polymer batteries. Our special-ists are glad to assist in selecting the most suitable material.

For instance, Ultramid® grades with optimized hydrolysis resistance such as Ultramid® A3WG6 HRX or A3WG7 HRX are already used for liquid-cooled batteries. These grades are able to withstand hot coolants at peak tem-peratures of up to 130 °C.

The particular properties of the high-performance elasto-mer Cellasto® are a major advantage over conventional elastic mounts, particularly in engine and powertrain mounts for electric vehicles. High-frequency noise is effectively decoupled. This is a particularly important consideration because the vibration behaviour of electric engines differs very greatly from that of combustion engines. High forces act here due to high-torque engines with high-frequency vibrations on the bearing positions. Cellasto® offers ampli-tude-selective damping and the possibility of achieving major deformations in compact installation spaces. Thus batteries for electric vehicles can be stored effectively. In certain cases, it is even possible to use the weight of the battery as a weight-neutral dynamic vibration isolator.

For battery casings themselves – which today are still fre-quently made of metal – the use of both short glass fiber-reinforced Ultramid®, long glass fiber-reinforced Ultramid® Structure as well as composite solutions with Ultracom® is possible, depending on the size and weight of the battery. Using plastics makes it possible to optimize the weight and space as well as to integrate many functions easily. Mod-ern fabrication methods which can be implemented on an industrial scale make a crucial contribution to the economic viability of the system as a whole.

BASF cooperates closely with partners and customers to come up with practical solutions. Beside obvious top-ics such as mechanical, thermal and electrical properties, issues relating to electromagnetic shielding, flame retar-dance and crash safety are also discussed. Especially in the event of accidents, plastics can offer crucial advantages. For instance, Ultramid® Structure is noted for its high energy absorption and good crash performance. Not least the electrical insulating capacity of plastics can be a crucial safety factor in the event of a crash.

The wide range of products and the wide experience of our experts can help our customers to find the best solutions for their particular application.

The charging technology for electric vehicles and plug-in hybrids constitutes an interface between the electrical system of the vehicle and the building installation. The single-phase or three-phase connection of the vehicles to the low-voltage grid via control cabinets or metering units is regulated, among others, by VDE14) Application Rule VDE-AR-N 4102.

The charging station is normally connected to the electric vehicle via a type 2 plug-in connector in accordance with IEC 62196-2 or what is known as the “Combined Charging System”. This was defined by SAE and ACEA as a stan-dard charging interface and should be a standard feature in all European vehicles from 2017. In this area, there is an increasing demand for flame-retardant plastics, which have been rarely used in the automotive industry until now.

13) VDA=German Automotive Industry Association 14) VDE = German Electrical Engineering Association

High-voltage connector

In the high-voltage system of hybrid and electric vehicles, voltages of up to 400 V and currents of over 100 A are achieved nowadays. Plastics are essential in guaranteeing the function and safety of components over the entire ser-vice life of the vehicle. Depending on the specific require-ment, special Ultramid® or Ultradur® grades can be used; also flame-retardant types are available where required. What should not be ignored are the possible high tempera-tures generated under high currents and mechanical loads as well as the exposure to vibrations caused by the rela-tively heavy high-voltage cables. With many high-voltage components, the color orange is also mandatory as a safety and identifying feature. The color has to be stable across the entire service life of the component, which might require special solutions particularly at high operat-ing temperatures. Many requirements are now specified in standards and industry instructions such as VDA13) LV214 and LV215.

Elastollan® is used for high-quality cable sheathings and cable components. It is indispensable for fulfilling the diverse technical demands on high voltage, traction and charging cables safely and permanently.

PROBLEM SOLVERSElectromobility

41

With charging cables made of Elastollan®, safe, lightweight and flexible cables and spiral cables (also at low tempera-tures) are possible. They make handling during charging easier for the car owner and he can store the cables more easily.

In addition to the plastics which are already established in automotive electrical systems, BASF – as one of the leading manufacturers of engineering plastics in the area of electrical installation – is able to offer a wide range of flame-retardant products. Detailed information regarding flame-retardant grades used in installation technology can be found in the brochure “Engineering plastics for the E & E industry”.

Engineering plastics are suitable for many electromobility applications which are not in public focus but are neverthe-less no less important. Examples include housings and components for power electronics, controllers or battery management systems. Since the number of units produced so far is still limited, they are frequently made from metal.

As manufacturing volumes rise, plastic solutions will become an increasingly attractive option. Highly filled or long glass fiber-reinforced thermoplastics can replace even metal alloy castings in electric coolant pumps or air-conditioning compressors. They are even conceivable for the housings of electric motors or transmissions. When it comes to climate control and heating in electric cars, plas-tics can be used for auxiliary heaters, heat exchangers, fans and blowers.

In order to jointly overcome the many challenges, a close and trustworthy relationship with vehicle manufacturers and the entire supply chain is particularly vital and sensible, especially in such a new application area. BASF experts from the different specialist fields are ready to help our cus-tomers to successfully implement projects.

4.2 Laser welding

A joining technique which has quickly become established in automotive electronics is laser welding. It joins together plastic components quickly, contactless, dust-free and without any mechanical loading. This makes it not only cleaner than adhesive bonding; it also prevents possible damage to sensitive components caused by vibrations, as can occur with other welding methods. In addition, com-ponents can be joined together using laser welding in a particularly secure and reproducible way.

Laser welding involves a laser-transparent component being joined to a laser-absorbing component. The absorb-ing component absorbs the laser energy and melts at the focal point. The conduction in the contact region also causes the laser-transparent component to be heated at the same time until ultimately both components fuse together.

Whereas all black standard materials more or less absorb laser light, the challenge is to develop laser-transparent materials.

The process of laser welding requires special materials which have good and above all consistent laser transpar-ency. BASF offers different proven Ultramid® combina-tions such as Ultramid® A3HG5 in black and uncolored, or special laser-transparent products such as the black Ultramid® A3EG6 LT. With the new Ultradur® LUX, BASF researchers have been able to in-crease the laser transparency to a high and constant level that has not previously been achieved for PBT. Products such as Ultradur® LUX B 4300 G4 and Ultradur® LUX B 4300 G6 are available in black and uncolored. These materials allow good process reliability and high welding speeds. But it is not just the laser trans-parency per se that is better; the quality of the laser beam which is allowed through has also been improved consid-erably. It can be shown that Ultradur® LUX allows approxi-mately two and a half times more light to pass through within the relevant wavelength than a conventional PBT GF 30, and this at the same time with a much lower wid-ening of the laser beam.

Laser welding and the laser-transparent Ultramid® and Ultradur® grades offer the user and processor numerous advantages:

great freedom of design hugely expanded process window shorter cycle times high process consistency high quality consistency greater flexibility no storage of other materials (e. g. adhesive and primer) no particle abrasion no mechanical loading of the molded parts low, locally restricted input of heat virtually wear-free method materials with different viscosities can be welded repair welding possible no vibrations caused by the welding process

The welding of pre-mounted assemblies even with sensi-tive electronic or mechatronic components is possible. The reasons: the components are not subjected to any mechanical loading when they are joined together and there is only a low, locally restricted input of heat into the material. The weld line can be monitored very pre-cisely. The polymer melt is expelled without lint or fuzz. This means that the flow behavior of air or liquids in laser beam-welded components is less prone to errors, which can be very important especially for sensors. In addition, the method works very flexibly, with almost no wear and no contact. With different versions such as contour, simul-taneous, quasi-simultane-ous or mask welding, the meth-od can be adapted perfectly for specific requirements.

In this special field our experts are glad to offer advice on the optimum choice of material and process technology.

4.3 Ultramid® EQ for sensitive automotive electrics

For reliable micro-electronics in sensitive automotive appli-cations such as control units and sensors, BASF has now developed a portfolio of various polyamide 6 and 66 grades that help prevent damage to circuits by electric corrosion.

The different Ultramid® EQ grades (EQ = electronic quality) are extremely pure, which means they have hardly any electrically active or corrosive contents, yet still offer good resistance to heat aging. They are subject to special qua-lity tests that cover raw material selection, the production process, and the analysis of the halogen content. Available globally, the portfolio consists of uncolored and black gra-des with glass fiber contents of 30 and 35 percent, which are also laser-markable. Portfolio (excerpt): Ultramid® A3EG6 EQ (PA66 GF30) Ultramid® A3EG7 EQ (PA66 GF35) Ultramid® B3EG6 EQ (PA6 GF30)

Ultramid® EQ has already proven itself in a range of appli-cations under harsh conditions.

Electronic assemblies in modern transmission control units or safety-related applications such as airbag and anti-lock systems are becoming ever more compact and complex. They are also often exposed to high ambient temperatures and aggressive media such as oil. The delicate circuits are often connected to semi-conductors via thin wires which is known as wire bonding. In such surroundings, disruptive effects such as corrosion, ion migration, electrolyte forma-tion, and creep currents can arise and in extreme cases cause entire assemblies to fail.

Plastics for housings and components have to be equip-ped in such a way that they do not react with the metals involved and thus prevent electronic failure.

All Ultramid® EQ grades have an organic heat stabilizer with a very low halogen content of less than 1 ppm. This prevents halogens like iodine or bromine from damaging metal wiring, ions from reacting with the metals, and undesired electric currents from arising.

In addition to the specified formula and complex produc-tion process, all Ultramid® EQ charges are checked care-fully. This ensures that the manufacturing process does not introduce any halogen contamination to the material. The relevant certificate is provided to customers if desired. The new Ultramid® EQ portfolio is also well-suited for use in electric and hybrid vehicles with elevated AC and DC voltages.

4.4 Lead-free soldering

Soldering with lead-free solder or solder that complies with RoHS15) has found its way into automotive electrics and electronics, as a result of voluntary commitment by the industry and the increasing global restrictions on the use of lead and lead alloys.

Lead-free solders require higher soldering temperatures and are thus more demanding with respect to the dimen-sional stability under heat of the plastics used. In accor-dance with DIN EN 61760-1 or J-STD-020C, the tempera-tures of the different soldering methods such as reflow, THR16) or wave soldering reach peaks of up to 265 °C for up to 40 seconds. In the case of manual rework/repair soldering, even higher peak temperatures may occur in individual cases.

Printed circuit board

PROBLEM SOLVERSLead-free soldering

15) RoHS = Restriction of Hazardous Substances 16) THR = Through Hole Reflow

These high temperatures can no longer be handled safely with many plastics. They may result, for example, in per-manent deformations if unsuitable plastic parts are insert-ed before the actual soldering process. Another problem can be caused by what is known as blistering as a result of evaporating moisture. What should also not be underes-timated are differences in the thermal expansion between the printed circuit board and the components to be sol-dered. This can lead to tension and stress during cooling after the soldering process. As well, this can place a heavy load on the solder joints or even result in the failure of sol-der joints or components.

47

With a melting point of 295 °C, Ultramid® T is a high-perfor-mance thermoplastic which is suitable for lead-free soldering methods. At the same time it can meet further important requirements for automotive electrics such as good mechan-ics and good processing properties.

Ultramid® T can be used with all conventional soldering methods. It is suitable for SMD17) and THR fitting.

Terminal carrier

PROBLEM SOLVERSLead-free soldering


The lower thermal expansion of the glass fiber-reinforced grades reduces the differences in thermal expansion, e. g. when soldering wire-to-board joints. Ultramid® T has a lower moisture absorption than e. g. PA66, which reduces the risk of blistering.

However, if components are stored for a longer time prior to soldering, moisture-proof packaging or pre-drying before the soldering process may be helpful in order to further reduce the risk of blistering.

4.5 Ultrasim®

Ultrasim® is BASF’s comprehensive and flexible CAE18) expertise with innovative BASF plastics. The calculation of component concepts on a virtual basis extends from choosing the appropriate BASF materials and correspond-ing material models, the virtual prototype and the ideal manufacturing process through to the finished component. With Ultrasim®, components can be tailored to meet spe-cific requirements – for efficient, lightweight components subject to high levels of stress and thus for long-term mar-ket success.

Building blocks of Ultrasim®:

integrative simulation injection molding process anisotropy mathematical part optimization failure modeling high speed tensile tests material modeling

Process

The modern calculation of thermoplastic components is very demanding for the developer. When it comes to the interaction between manufacturing process, compo-nent geometry and material, only an integrated approach can lead to an ideal component. Plastics reinforced with short glass fibers in particular have anisotropic properties depending on how the fibers perform in injection mold-ing. Modern optimization methods support the component design and can improve it in every phase of its develop-ment.

BASF’s Integrative Simulation incorporates the manufactu-ring process of the plastic component into the calculation of its mechanical performance. Using the numerical FE filling simulation as the basis for the calculation of the fiber orientation, each point of the component is assigned corre-sponding anisotropic material characteristics.
